The tapes shall be sufficiently flexible to enable it to turn satisfactorily on a machine where it has to turn through 180° on a 6 mm diameter roller, yet stiff enough to enable it to be easily fed through the throat of a punch block or a similar device.

With the tape oriented as shown in Figure 1, and the observer looking down onto the tape, the direction of forward tape movement is from right to left, and the first character of data (the most significant character as entered from a typewriter-like device) is the one farthest to the left (1st).

A coil of punchedtape, the first character of data being at the free, outer end, shall run in such a manner whilst turning anti-clockwise that the reference edge is the one, nearest to the observer (see Figure 3), and in addition, so that the title or arrows appear on the outer surface.

Punched tape - Biocrawler(Site not responding. Last check: )

Punchedtape is an old-fashioned form of data storage, consisting of a long strip of paper in which holes are punched to store data.

The earliest forms of punchedtape come from weaving looms and embroidery, where cards with simple instructions about a machine's intended movements were first fed individually as instructions, then controlled by instruction cards, and later were fed as a string of connected cards.

Punchedtape was eventually also used as a way of storing messages for teletypewriters.

The tapepunch, rather than punching out the usual round holes, would instead punch little U-shaped cuts in the paper, so that no chad would be produced; the "hole" was still filled with a little paper trap-door.

Punchedtape was used as a way of storing messages for teletypewriters.

In each group, the first punch represents "1"; the second, "2"; the third, "4"; and the fourth, "8." Thus, a combination of 1, 2, or 3 appropriate punches in a given group represents digits from 1 to 9.

A paper tape is moved upward through the punch assembly in the center of the instrument.

The mechanically punchedtape is still widely used at this time (1996) and is considered very practical for field use where temperature, moisture, and power conditions are widely variable.

The ASR33 tape reader was purely mechanical; 8 spring loaded fingers would be thrust into the tape (one character at a time), an assortment of rods and levers would sense how high the finger rose, which told it if there was a hole in the tape at that position.

is what actually reads the data from the perforated tape, encoded as rows of up to eight holes punched across the width of the tape, and turns them into electrical symbols, that are distributed to the other components by the interconnecting wires.

The tapepunch plugs onto the Windows serial port, and with a FOSSIL driver and my serial program, the tape-image file is copied out to the tapepunch.

Tapes can be played from the middle (of course skipping earlier data), since all devices will re-sync on the start of the next data record.

Punchedtape or paper tape is a largely obsolete form of data storage, consisting of a long strip of paper in which holes are punched to store data.

The stencilling tape according to claim 3, wherein the adhesion of the adhesive film is lower than the cohesion of the adhesive film, the adhesion of the adhesive film is reduced when the adhesive film is extended, and the adhesive film exhibits a ratio of peel strength to tear load of at least 1:1.5.

The stencilling tape according to claim 8, which is covered on one or both sides with a release paper or release film, and the release paper or release film on at least one of said sides is punched.

The stencilling tape according to claim 10, wherein the adhesion of the adhesive film is lower than the cohesion of the adhesive film, the adhesion of the adhesive film is reduced when the adhesive film is extended, and the adhesive film exhibits a ratio of peel strength to tear load of at least 1:1.5.

paper tape readers accessed the data by means of springy wires (one per channel), which could make electrical connections to conducting plates under the tape wherever a hole was present.

The higher-speed opto-electronic models used rubber rollers to drive the tape, but the sprocket holes remained, because light passing through them could be detected and used to generate synchronization pulses.

Of course, it was still necessary to be able to differentiate between the two ends of the tape, so the operators used scissors to shape the front-end into a triangular point, thereby indicating that this was the end to be stuck into the tape reader.

In a similar manner to Sir Charles' telegraph tape, the designers of the early computers realized that they could record their data on a paper tape by punching rows of holes across the width of the tape.

In the original slower-speed readers, the small sprocket holes running along the length of the tape between channels 2 and 3 were engaged by a toothed wheel to advance the tape.

However, although paper tapes and punched cards may seem delightfully antiquated, many institutions, including universities, continued to use these forms of data storage well into the 1980s, and both techniques are still to be found in the odd technological backwater to this day.

The tapes hanging down could lengthen and shorten, and for program tapes and the table lookup unit we cemented the tape end-to-end into short loops (yes, someone had had to provide the jig).

It passes through a punch unit in the square box at the upper left and is punched with two round sprocket holes and up to seventy-eight conventional IBM rectangular holes.

Each punch is followed by 10 reading stations, or the tape from the first may pass to all 30 reading stations.

The tape number is determined t;y the order in which the tapes are submitted to the generator routine; it is not printed for the first tape.

The binary object tape is not affected by this error; the con- trol statement entered via the Teleprinter is the one used by the Assembler.
